I have been directed to a new, very short paper from Frank Tipler, "Testing Many-Worlds Quantum Theory By Measuring Pattern Convergence Rates", in which we have yet another alleged experimental test for MWI. Specifically, Tipler thinks he can derive the Born probabilities. He starts by distinguishing between the idealized asymptotic scatter of infinitely many measurements (say, in the double-slit experiment) and the growing actual pattern of always-finitely-many measurements, and then uses Bayes to say something quantitative about the rate at which the former approximates the latter. Without having examined the argument in any depth, I am going to predict that if it holds up, it will be possible to reproduce it within a non-MWI framework (e.g. standard quantum measurement theory). But Bayesian many-worlders may wish to look at the details.
